Answer:
∠C = 37° ,
AB = 26.54 cm ,
BC= 33.27 cm
Step-by-step explanation:
Given that in triangle ABC
∠A = 39° AC = 20 cm
∠B = 104°
∵ sum of all the three angles of triangle = 180°
So, ∠C = 180° - ( ∠A + ∠B)
∠C = 180° - (39° + 104°)
∠C = 37°
Now Tan 37° =
Or, AB =
So, AB = 26.54 cm
Again, Sin 37° =
So, BC =
Or, BC =
∴ BC= 33.27 cm
Hence ∠C = 37° , AB = 26.54 cm , BC= 33.27 cm Answer
B) 7
C) 8
D) 9
The question is an illustration of divisions.
Cindy needs to buy (c) 8 packs
The given parameters are:
The number of packs is calculated by dividing the total number of invitation by the number of invitations in each pack.
So, we have:
Cindy needs 7.5 packs.
Since the packs cannot be split, Cindy must buy the closest number of packs greater than 7.5
So, we have:
Hence, Cindy needs to buy (c) 8 packs
